Analysis of maintenance, testing and troubleshooting of cassette water meters

1. How to maintain the cassette water meter?

Your cold water meter is also cold in winter, so the maintenance of the cassette water meter is especially important. Correct maintenance can increase the service life of the cassette water meter and ensure the accuracy of measurement. How to maintain the cassette water meter correctly?

When using the cassette water meter, try to ensure that it can operate normally and place it in a horizontal position. When in use, pay attention to the cleanliness of the cassette water meter around the cassette water meter, avoid the corrosion of the cassette water meter by some acid and alkaline substances, and also ensure the period of moisture resistance, which will lead to the damage of the cassette water meter. Errors caused by damage, or even damage to the cassette water meter; generally, after the cassette water meter is used for a long time, some scale will be generated, and the formation of these ditches in the cassette water meter can easily lead to the cassette water meter Measurement errors may even lead to errors in its transmission. Therefore, regular maintenance and the selection of cassette water meters are very important. Regular cleaning is a necessary maintenance step for using cassette water meters; it is also impossible to place things on the cassette water meters, because long-term placement of things will cause In case of damage to the cassette water meter, if a problem is found in the cassette water meter, and a bad state is found, do not open the lead seal of the cassette water meter privately. The unauthorized operation may cause permanent damage to the cassette water meter. Will bring unnecessary losses to users. The cassette water meter must be placed horizontally during transportation. After all, the cassette water meter is an instrument, not only to ensure that it can be used, but also that it can accurately measure and transmit data.

2. The quality inspection process of cassette water meter?

Water meter pressure test equipment is an inspection device used to test the strength of water pressure and the sealing performance of cassette water meters? Commonly known as water meter pressure table. The water meter pressure table can not only detect the water pressure and the sealing performance of the cassette water meter? It can also test the performance of the tempered glass and the water meter housing of the wet water meter.

The components of the water meter pressure test equipment include: clamp meter device components, booster mechanism components, pressure display instrument components, timer components and control valves. Taking into account the convenience and flexibility of the use of cassette water meters and the saving of energy and space? The pressure test equipment can be combined with a single table or series water meter detection device? It is convenient and flexible and saves space.

3. The composition and working principle of each component of the cassette water meter:

1. Parts of the clamp meter: the cassette water meter generally adopts hydraulic transmission. The installation and use methods can be vertical or horizontal;

2. Booster mechanism components: According to the non-compressible nature of the liquid and the principle of static pressure transmission, the cassette water meter uses a booster piston cylinder as a device to meet the pressure required during the test. But this method is only suitable for large-caliber water meters? Because the test volume of small-caliber water meters is small, and the pressure caused by the electric pressure test pump is large, it is not suitable for use;

3. Pressure display instrument component: It is an instrument used to indicate the pressure of the cassette water meter test and reflect the performance indicators of the test system or the leakage status of the tested water meter. Generally, the cassette water meter uses a pressure gauge with an accuracy of level 1 or 1.5? The measuring range is 0～2.5Mpa? The dial diameter is above Y100. For high-pressure water meters, the pressure-bearing capacity of the piping system and the range of the cassette water meter should reach more than twice the nominal pressure of the high-pressure water meter before it can be used safely;

4. Timer component: The timer, as its name implies, is a device that measures the test time. The cassette water meter can be a mechanical stopwatch or an electronic stopwatch.

Fourth, the common troubleshooting of cassette water meters

After many years of experience of Cassette Water Meter Co., Ltd., the following common troubleshooting of cassette water meters are summarized:

1. Failure phenomenon: The valve of the cassette water meter is closed. Inspection and disposal: see if it shows power shortage, swipe the card to check if it shows interference or the remaining water is not enough.

2. Fault phenomenon: display card error 1 or card error 7. Inspection and disposal: re-swipe the card for the cassette water meter.

3. Failure phenomenon: The cassette water meter displays error 1. Inspection and disposal: contact the management department.

4. Failure phenomenon: display error 2. Inspection and disposal: contact the management department.

5. Failure phenomenon: the cassette water meter displays "off" and the remaining volume is less than the alarm water volume and the alarm water volume is less than 2m3. Check and disposal of cassette water meter: purchase water.

6. Fault phenomenon: "Lack of power" is displayed. Inspection and disposal: please replace the battery.

After checking the above phenomena, the cassette water meter still cannot be restored, please contact the local management department; electronic metering control products, please do not disassemble it privately, otherwise, you will be responsible for the consequences.

The cassette water meter is equipped with valves, electronic modules, and batteries on the ordinary water meter. The former valve is a structural increase, while the valve is dynamic. Since the day the cassette water meter was born, the valve has become the key to the cassette water meter. No matter which valve has more or less problems of this kind. The latter is an increase in electronic devices. We all know that the reliability of electronic products is far lower than that of mechanical products, because there are many quality factors of microelectronics that we can't see, and even the combination of cassette water meter devices will change. Therefore, if the added valves and electronic devices are not handled well, it is the source of the quality problems of cassette water meters.
